The following fields of ZEXP-MAP-STATS-LINE-NCSM (fields
ZI-FRAMES-SENT through ZU-FRAMES-RECV) contain counts of the
numbers of level-2 frames sent and received.
ZI-FRAMES-SENT contains the total number of I-frames sent.
ZI-FRAMES-RECV contains the total number of I-frames received.
ZS-FRAMES-SENT contains the total number of S-frames sent.
ZS-FRAMES-RECV contains the total number of S-frames received.
ZU-FRAMES-SENT contains the total number of U-frames sent.
ZU-FRAMES-RECV contains the total number of U-frames received.
The following fields of ZEXP-MAP-STATS-LINE-NCSM (fields ZBCC-
ERRS through ZFRAMES-ERR) relate to the numbers of errors in
frames received from the modem.
ZBCC-ERRS contains the total number of BCC/VRC errors and FCS
errors detected in driver frames received by a bit-synchronous or
byte-synchronous controller.
ZALLOC-ERRS contains the total number of buffer-allocation
failures.
ZQUAL-ERRS contains the total number of line-quality errors.
ZFRAMES-TOTAL contains the total number of frames handled.
ZFRAMES-ERR contains the total number of received frames that had
errors. The count of error frames is incremented each time one
or more of the following errors occurs while receiving a frame:
• A BCC/VRC error or an FCS error on a frame received by a bit-
synchronous or byte-synchronous controller
• An overrun error due to unavailability of resources
• A one-byte frame (for LAPX protocol only)
The count is also incremented each time a level-2 timeout occurs
while level 2 is waiting for an acknowledgment of an information
frame.
